Question

def punctuation(x,y):
 if len(x) == 0:
     return y

 if '.' in x[0]:
     x[1] = x[1].capitalize()
     return punctuation(x[1:],y.append(x[0]))
 elif '!' in x[0]:
     x[1] = x[1].capitalize()
     return punctuation(x[1:],y.append(x[0]))
 elif '?' in x[0]:
     x[1] = x[1].capitalize()
     return punctuation(x[1:],y.append(x[1]))
 else:
     return punctuation(x[1:],x[0])


 z = ['!a','b'] 
 punctuation(z,[])

Hope to get [‘!a’,’b’] ,which means if the first item contains (!,?,.),the second one become capitalize

Q3_p1 = "Enter the digit on the phone (0-9): "
Q3_p2 = "Enter the number of key presses (>0): "



def enter_msg(n):
    x=raw_input(Q3_p1)
    y=raw_input(Q3_p1)
    Jay = Jay_chou(x,y)
    return Jay

 def Jay_chou(d,n):

     if d==0: return " " 
     elif d==1: return [".", ",", "?"][n%3-1]
     elif d==2: return ["a", "b", "c"][n%3-1]
     elif d==3: return ["d", "e", "f"][n%3-1]
     elif d==4: return ["g", "h", "i"][n%3-1]
     elif d==5: return ["j", "k", "l"][n%3-1]
     elif d==6: return ["m", "n", "o"][n%3-1]
     elif d==7: return ["p", "q", "r", "s"][n%4-1]
     elif d==8: return ["t", "u", "v"][n%3-1]
     else: return ["w", "x", "y", "z"][n%4-1]


 enter_msg(2)

i don’t know why i got the error
i see this:

Enter the digit on the phone (0-9): 1

Enter the digit on the phone (0-9): 1

['1', '1']

TypeError: not all arguments converted during string formatting

Answer 1

For the second probelm:

you’re passing strings to Jay_Chou() in Jay = Jay_chou(x,y), instead you should pass integers. In your case the n%3 part actually tries to do string formatting instead of modulus operation.

raw_input() returns strings, you need to convert them to integers using int()

so you get this error:

In [13]: '1'%3
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-13-39edc619f812> in <module>()
----> 1 '1'%3

TypeError: not all arguments converted during string formatting

try this:

Jay = Jay_chou(int(x),int(y))

then it outputs:

Enter the digit on the phone (0-9): 3
Enter the digit on the phone (0-9): 4
d

#and for 1,1:

Enter the digit on the phone (0-9): 1
Enter the digit on the phone (0-9): 1
